This invention relates to ticket-printing machines, and more particularly to a printing machine having provision for the mechanical setting and restoring of type.

The invention is particularly applicable to a machine for printing series of tickets or the like, in which one or more of the characters re quires frequent changing and provides for making the necessary type changes without materially delaying the printing operations.

An object of the invention is to provide a simplified type-setting mechanism in a machine of the character specified.

Another object is to provide for the rapid restoring and resetting of the type.

A further object is to provide for selectively resetting one or more of the type characters without disturbing the setting of the other characters.

position for printing.

A still further object is to provide a simple, convenient and dependable device of the type above indicated.

In one embodiment of the invention, the typesetting machine comprises a pair of aligned stacks of rooved type carriers, one stack comprising a type-storage magazine and the other stack comprising a type-receiving magazine and printing form. The type pieces are placed endtoend in the storage magazine in rows which are adapted to slide into the type-receiving magazine. Means is provided for sliding the various rows selected distances into the typereceiving magazine and for lockin the type in The longitudinal position of the rows of type with respect to the magazines determines the particular type face which is brought into printing position. The type-receiving magazine serves as a printing form and is adapted. to cooperate with suitable inking means and to be brought into printing relationsh p with the paper-supporting bed. After the printing operation, the type-receiving magazine is again brought into alignment with the type-storage magazine, whereupon the type may be restored or reset as desired.

Althou h the various novel features which are believed to be characteristic of this invention will be particularly pointed out in the claims appended hereto, the invention itself, as to its objects and advantages and the manner in which it may be carried out, may be better understood by referring to the following description taken in connection with the accompanying drawings forming a part thereof, in the various figures of which like reference characters have been used to designate like parts.

In the following description and in the claims, various parts are referred to by specific names for convenience, but they are intended to be interpreted as broadly as the state of the art will permit.

In the embodiment of the invention illustrated in the drawings, the ticket-printing machine is shown as comprising a main frame or stand having uprights 20 and side members 21, 22 and 23, which are joined thereto in any suitable manner and form supports for parts of the apparatus to be described. Cross members 24 are carried by side members 23 and carry printing head supports 25, which may be secured thereto by bolts 26 and spacing members 30 (Figures 1 and 3). The printing head supports 25 carry type magazine supports 31 and a printing bed or paper support 32 (Figure 5). The paper support 32 may comprise a pair of side members 33 (Figure 8) which are pivoted to the supports by bolts 34 extending through elongated arcuate slots 35, which are formed in said side members 33. The side members 33 bear against adjusting screws 36, which are threaded in blocks mounted on said printing head supports 25. The side members 33 also carry a bed plate 41, which is adapted to receive the paper or the like to be printed, and a stop member 42 which is adapted to control the position of the paper during printing.

The type magazine supports 31 carry a pair of type magazines'43 and 44 (Figures 5-7), which are adapted to constitute the type-storage magazine and the type-receiving magazine respectively. The type-storage magazine 43 comprises a stack of slotted type carriers 45, each of which comprises a channel plate 46 having type-spacing means 50 secured thereto or integrally formed therewith and carrying a cover plate 51, which is secured thereto by screws 52. The spacing means 50 form a plurality of channels adapted to receive rowsof type 53, which are placed end-to-end in the various channels, as illustrated in Figures 8 and 10, with the printing face of each of the type pieces abutting against the baseof the next type piece.

The various type carriers are mounted on brackets 54, whichare supported on cross members secured to magazine supports 31.

The position of the rows of type in the various channels is controlled by pushers 56 (Figures 8 and 10), which are mounted on flexible wires 60 adapted to slide in flexible cables or sheaths- 61. Said pushers 56 are adapted to slide in the various channels and to hold the rows of type in various selected positions. One

- .endof each of the flexible cables 61 is secured l in a yoke 62 (Figure 6) as by set screws 63.

The other end of certain of the flexible cables may be secured by set screws 64 to a cross bar 65 (Figures 1, 3 and 17) which may, for example, be supported on a cross member 66 carried by side members 21 of the main frame. Certain others of the flexible cables may be secured in guide bars '76 (Figures 1, 12 and 13), which are pivotally mounted on a rod 71 and spaced by spacing means 72. The rod '71 may be secured to the side members 21 as by yokes '73.

spectively secured to the lower ends of a plu-,

rali'ty of levers 80, which are pivoted on a rod 81 mounted on the side members 22 by means of yokes 82 and carrying spacing washers 83, by which the levers are properly spaced (Figures 1 and 3). The upper ends of the levers extend through slots 84 in an arcuate index plate 85, which is mounted on brackets 86 supported by the side member 23 of the frame. The ends of theflexible wires 60 located within the grooves '74 of the guide bars are preferably curved into U-shaped form, .as illustrated in Figure 12, and secured to the levers at a point located at the side or" the guide bars '70. This causes the wires to seat within the grooves 74 and eliminates any tendency of the wires to bend transversely of said grooves. The guide bars 76 are preferably curved about the rod 81 as a center so that the grooves 74 are properly aligned with the lower ends of levers 80 throughout the movement of said levers. It is obvious that the guide bars may be utilized with all of the wiresfiu if desired, in the form shown the bars are used to support only the wires which have a comparatively long range of movement. The guide bars are particularly important for the latter wires, inasmuch as the tendency to buckle is greater for wires extend a greater distance beyond the end oi the flexible cables 61. i

The type-receiving magazine comprises a plurality of grooved type carriers so (Figures 3, 5, 8 and 10), which are similar in form to the type carriers 45 above described. The type carriers 90 are supported by side brackets 91 and The brackets 92 extend upwardly past the type carriers 2G to form ears 93, which are pivoted to iinlrs 94, as by pins 95. The links 24 are pivoted, as at St, to the magazine supports 31.

The brackets 91 are extended downwardly past the type carriers 90 and are pivoted, as'by pins 100, to links 101 which are rigidly secured to a shaft 162. The shaft 162 is mounted in suitable bearings in the printing head supports 25, as shown in Figure 1, and carries an operating handle 103.

The brackets 91 are also provided at their lower ends with extensions 104 carrying a ribbon'spool support 165 on which a ribbon 105 is adapted to be wound. The support 165 also carries a ratchet 110 cooperating with a pawl 111 to advance the ribbon as the machine is operated. The pawl 111 (Figures 8 and 19) is mounted on a shaft 112, journaled in one of the magazine supports 31 and extending beyond said support to carry a handle 113, by which the pawl may be held out of engagement with the ratchet 110 to permit the ribbon to be rewound. The 111 is held in operating position with respect to the ratchet 110 by-means of a spring 114, which may be secured to a stationary stud 115 on the magazine support and may bear against the top surface of said pawl.

A pin 116 may be provided to limit the movement of the pawl when it is out of engagement with the ratchet 110.

:he ribbon may be carried on a shaft 12% journaled in the printing head supports 25 and extended laterally to carry a handle 121 (Figures 4-, 8 and 10), by which the ribbon may be.

rewound. The ribbon is threaded from the shaft past the shaft 102 and past a supporting member 122, which is carried on the links 101, and thence to the ribbon spool on the support 105.

A frame 124 (Figures 5, 3 and 10) having side members 125 may be slidably mounted the brackets 91, as by screws 126, carried by said brackets and cooperating with elongated slots formed inthe side members 125. The frame 124 carries a plurality of locking bars 131, which are wedge-shape in cross section are adapted to extend across the various type carriers 96. The top surface of each carrier is recessedto receive said bars and to permit the bars to engage the type pieces. The various type pieces are provided with wedge-shaped grooves 132,.

lei]

which are adapted to receive the locking bars 131 by which the type pieces are aligned and locked in position. The frame 124 is held in looking position by a spring 133, which is secured between the side pieces 125 and brackets 91. The side pieces 125 also carry pins 134, which are adapted to cooperate with a slot 135 in a pivoted lever 136 (Figure 5) to elevate the frame and to release the locking bars 131 from the type or to positively force the locking bars 131 into engagement with the type and to cause the wedge-shaped surfaces to properly align the same. The forked end of the lever 136 is provided with a shoulder 137, which is adapted to engage the pins 134 and to thereby securely lock the type-receiving magazine 44 against the typestorage magazine 43 when the lever 136 has engaged the pins 134 to hold the frame 124 in elevated position.

The lever 136 is pivoted, as at 140, in the magazine supports 31 and is extended, as at 141, to engage a link 142 (Figures 3, 4 and 10) The link 142 is pivoted to a lever 143, which extends through a slot 144 in the index plate and is pivoted about the rod 81. A spring 145 may be secured between the lever 143 and a portion of the frame of the machine to normally hold said lever in retracted position, whereby the lever 136 is normally disengaged from the pins 134.

The upper part of the frame 124 is provided with a cam surface 150 (Figures 8 and 10) which is adapted to engage a cam surface 151 formed of a cross member 152, carried by the links 101 to firmly seat the frame 124 and to thereby bring the locking bars 131 into locking engagement with the grooves 132, formed in the type pieces when the type-receiving magazine 44 is brought into printing position, as illustrated in Figure 10, thereby preventing the printing force from causing the locking bars 131 to unseat and permit the type to move from printing position.

An aligning member 154 (Figures 10 and 16) is carried by the magazine supports 31 and has a cam surface 155, adapted to engage the lower edge of the stack of type carriers comprising the type-receiving magazine 44, and to thereby direct the type-receiving magazine into correct alignment with the type-storage magazine 43.

In a machine adapted to print the ticket illustrated in Figure 2, certain of the type, for example the type designating Quality, P. G. No., Yds, Color and Order, may be permanently set, Whereas the characters referring to the above items may be changed at frequent intervals. The type to be permanently set may be secured in the proper type channels by means of set screws 160 (Figure 9) and the member 154 may be recessed, as at 161 (Figure 16), to provide clearance for the set screws 160. It is to be understood that any desired number of the type may be permanently set by means of these set screws and the remaining type spaces may be adjusted by means of the sliding rows of type above described.

The index plate 85 may be provided with a plurality of notches 162 adapted to engage lugs (not shown) on the levers 80 to properly align the levers in the various selected positions. The

levers 80 may be mounted slightly off-center with to visually designate the setting of the levers 80;

For this purpose,'the levers may be provided with arcuate plates 164 (Figures 14 and 15) having suitable designations thereon and adapted to register with a slot 165 formed in the index plate 85. r

In the operation of the above-described device, the permanent designations are set in the proper type channels and type pieces are locked therein by means of the set screws 160 (Figure- 9) The rows of type are then applied'to the remaining channels, preferably in numerical or alphabetical order or, at any rate, in the order designated upon the index plate 85. These type pieces are applied in such' relative positions that, when they are locked by the locking bars 131 and the type-receiving magazine 44 is removed from alignment with the type-storage magazine 43, the exposed type faces are in printing position. The receiving magazine consequently provides a type form by which printing is effected.

In order to set the desired type, the various levers 80 are moved a distance corresponding to the designations desired to be set, thereby causing the pushers 56 to move the various rows of type upwardly from the type-storage magazine into the type-receiving magazine. During this type-setting operation, the lever 143 is operated against the tension of the spring 145 to actuate the lever 136 and to cause'the same to elevate the frame 124 carrying the locking bars 131. This permits free movement of the rows of type within the various type channels.

After the proper type has been set, the lever 143 is released, thereby permitting the locking bars 131 to engage the grooves 132 in the type pieces which are in alignment therewith and to securely look within the type-receiving magazine the type which has been pushed into said magazine in the setting operation.

A ticket or the like to be printed is then placed upon the printing bed 32 and the handle 103 is operated to cause pivotal movement of the links 101.' The type-receiving magazine 43 thereby pivots about the links 101 and 94 into the printing position illustrated in Figure 10. In this position, the ribbon 106 extends between the type faces and the ticket to be printed. Hence, the pressure of the type faces transfers ink from said ribbon on to said ticket. At the end of the printing operation, the handle-103 is moved in the reverse direction to again swing the typereceiving magazine 43 into alignment with the type-storage magazine 44, the cam surface 155 serving to insure the correct alignment. Thereafter, a second ticket or the like may be printed with the type as previously set up, or certain of the type designations may be changed in order to print, for example, a different order number on the succeeding ticket. To change the type, the lever 143 is moved to release the locking bars, whereupon the proper lever 80 may be moved to its new position and the type relocked. It will be noted that this type-resetting operation is simple and rapid and does not appreciably delay the successive printing operations. Furthermore, the shoulders 13''] of the levers 136 engage the pins 134 so as to securely lock the type-receiving magazine against movement while the frame 124 is elevated to release the type for resetting This prevents the typereceiving magazine from being moved except when the type is securely locked therein.

The cam surface 151 engaging the surface 150 on the frame 124 securely locks the type at the Mil Ito receive the ten figures.

moment of printing and preventsthe printing pressure from deranging the'same. This sur'. face also prevents the type-receiving magazine from being brought into'printing position unless the type is locked therein.

Although an inking ribbon has been shown for purpose of illustration, it is obvious that other inking means may be employed if desired and also that the ribbon may be automaticallywound or rewound by suitable mechanism well known in the arti In the form.,illustrated, the movement of the type-receiving magazine into alignment with the type-storage magazine after each printing operation causes the ratchet. 110 to engage the pawl 111 and to advance the ribbon 106 one step. This mechanism is shown, however, merely by way of illustration and not as a limitation of the present invention.

It will be noted that certain of the slots 84 and certain of the type carriers are shown to be of greater length than others. This, in the form illustrated, is to permit these type carriers to receive the twenty-six letters of the alphabet, whereas the remaining type carriers are adapted It is obvious that the number of carriers to which letters are applied and to which figures are applied may be varied as desired in order to suit any particular case; The guide bars '70 are of. importance 1; Where the flexible wires extend beyond their supporting cables a substantial distance, inasmuchasa long, unsupported section of the Wire would tend to buckle during the type-setting operation; The pivotal support for the guide I bars permits them to compensate for any inaccuracies in position with respect to the movement of the levers and thereby prevents them from binding or interfering with the free movement of the levers. It is also to be noted that the ,j type magazines are mounted at a substantial angle to the horizontal. This angle is sufficient to cause the type to slide downwardly into a type receiving magazine when the pushers, 56 are retracted. It is obvious, however, that mejchanical means for causing positive return of the type could be employed if desired. It is also obvious that various other means may be employed for releasing the locking bars 131 and that the lever 1&3 has been shown for this pur- ;pose merely as a matter of convenience.

Although one embodiment of the invention has been shown by way of illustration, it is to be understood that the invention is not to be limited thereto but only in accordance with the ;following claims when interpreted in view of the prior art. v
